Objective:
The objectives of this research project are to: (1) test the hypothesis that patients with preexisting respiratory, cardiovascular, or diabetic conditions have an enhanced mortality response to particle exposures; and (2) assess the effects of gaseous copollutants as alternative predictors of mortality and the degree to which they modify the response to particulate matter (PM).
This is one of 10 projects funded by the Center. The progress for the other nine projects is reported separately (see reports for R827353C001 through R827353C003, and R827353C005 through R827353C011).
Progress Summary:
The identification of populations that are especially susceptible to PM health effects can further our understanding of biologic mechanisms of heart and lung disease attributable to PM. Our previous research has shown that individuals with diabetes are at higher risk from exposure to PM. We have published several papers addressing this issue. A recent paper examined effect modification by concurrent diagnosis of diabetes overall and by age group in four U.S. cities and found that individuals with diabetes have twice the risk of a PM10-associated cardiovascular admission compared to those without the disease (Zanobetti and Schwartz, 2002).
To further examine susceptibility by diabetes observed in these population studies, we obtained clinical information to gain insights on potential biological mechanisms. With researchers at the Joslin Diabetes Center and Beth Israel/Deaconess Hospital, we analyzed the relationship between air pollution and both inflammation and vascular reactivity in more than 200 greater Boston residents participating in clinical trials. We used particle data (PM2.5, particle number, black carbon, and sulfate) measured at the Harvard School of Public Health site established by the Center. Both black carbon and sulfate particles appeared to have effects on vascular reactivity and endothelial function, especially among people with diabetes (O'Neill, et al., submitted, 2004a). Additional analyses have shown associations between increased particle levels and blood markers of inflammation, including intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and von Willibrand's factor. Manuscripts describing these results are in preparation.
We have continued to explore factors influencing vulnerability to temperature-related mortality. Data on air pollution compiled for Center research projects have been used to control for confounding. In a study of seven U.S. cities, lower educational attainment, black race, and dying outside a hospital were markers of vulnerability to death on extreme temperature days, controlling for PM10 exposure (O'Neill, et al., 2003b). In a follow-up analysis, we found that air conditioning prevalence explained some of the observed racial disparities in heat-related mortality in four of these cities (O'Neill, et al., in review, 2004). An additional analysis found that air pollution and epidemics were important confounders of temperature and mortality associations and suggested inclusion of PM10, ozone, and epidemic periods in future analyses, which can be used in forecasting health impacts of climate change (O'Neill, et al., submitted, 2004b).
The case-crossover approach also was used to examine the PM10-associated risk of emergency hospitalization for myocardial infarction during 1985-1999 among elderly residents in 21 U.S. cities. The results from this study showed increased risk of hospitalization for myocardial infarction for diabetics. Effect sizes roughly were doubled in persons with chronic obstructive pulmonary disease or concurrent pneumonia compared to those without (Zanobetti, et al., 2004).
During the past year, we examined the association of PM2.5 and changes in blood markers of cardiovascular risk, including lipid profiles and markers of acute systemic inflammation, in the Pravastatin Inflammation C-Reactive Protein (CRP) Evaluation study; a large, national randomized trial on the use of statins to lower such risk factors. In the placebo group, we found associations between PM2.5 and CRP total cholesterol and low-density lipoprotein. For the same outcomes, the associations were not significant in the group taking statins (Zanobetti, et al., 2004).
Future Activities:
We will continue to: (1) test the hypothesis that patients with preexisting respiratory, cardiovascular, or diabetic conditions have an enhanced mortality response to particle exposures; and (2) assess the effects of gaseous copollutants as alternative predictors of mortality and the degree to which they modify the response to PM.
